This short course should be of interest to geotechnical engineers, structural engineers, and civil engineers who wish to have a better understanding of the current state-of-the-art with respect to the analysis and design of shallow and deep foundations. All key concepts and terminology will be explained and emphasis will be placed on the practical application of the information provided.

Objectives

The main objective of this course is to equip the participants with the needed tools to select the best foundation solution for each particular project. After completing the course participants should be able to design shallow and deep foundations and supervise their construction. The course philosophy is to provide the participants with the information they need to design foundations at the state of the art.

Who Should Attend

Structural, civil and geotechnical engineers, consulting engineers, technicians and technologists, public works and construction department employees of federal, provincial, and municipal governments and engineers responsible for large industrial, commercial, or institutional facilities who must deal with different types of foundations, and foundation construction contractors.

Special Features

The 3-day course consists of a series of lectures and workshops. Worked examples with numerical reference reinforce the lecture content. Case studies which illustrate the full range of problems are a feature of the course. There are workshops conducted under instructor guidance on bearing capacity, shallow and deep foundation design, settlement analysis, and a workshop for design examples.

Instructor

Dr. Hany El Naggar, PhD, P.Eng.

Associate Professor of Geotechnical Engineering, Dalhousie University

Hany has more than 20 years of experience in civil construction, geotechnical, and structural engineering and research in Canada and overseas. He has participated in several structural and geotechnical investigations, and is experienced in analysis and design of foundations and soil-structure interaction of buried infrastructure. Dr. El Naggar and his research team has investigated the soil-structure interaction (SSI) effects around buried infrastructure, explored innovative use of tire derived aggregate (TDA) as a buffer zone to create stress arching and reduce demand on rigid culverts, proposed an earth pressure reduction system using geogrid reinforced platform bridging system to reduce stresses on buried utilities, and developed innovative “cellular” precast concrete pipe system. He also has developed a simplified technique to account for the group effect in pile dynamics, and closed form solutions for the moments and thrusts in jointed and un-jointed composite lining systems, designed several foundation systems ranging from machine foundations subjected to dynamic loads to raft foundations for underground structure, as well as several tunnels and underground structures in the United States, Europe, and Canada.

The findings from Dr. El Naggar’s research have been reported in more than 65 technical publications covering both experimental and numerical work in the fields of soil-structure interaction, buried infrastructure and concrete pipes. He is the recipient of the 2005–2006 Outstanding Teaching Award from the Department of Civil and Environmental Engineering at Western. Prof. El Naggar won the 2006 L.G. Soderman Award, the 2005 R.M. Quigley Award, and the 2004 Milos Novak Memorial Award. Dr. El Naggar is the current chair of the Buried Structures Committee, CSCE, also, he is member of the technical committee on buried structures of the Canadian Highway Bridge Design Code (CHBDC). In addition, he is the current editor-in-chief of the International Journal of Civil Infrastructure.
